DETAILED DESCRIPTION

Aspects of the present disclosure are directed to ball grid array storage for a memory sub-system, in particular to memory sub-systems that include a plurality of ball grid array (BGA) components. A memory sub-system can be a storage device, a memory module, or a hybrid of a storage device and a memory module. Examples of storage devices and memory modules are described below in conjunction with FIG. 1. In general, a host system can utilize a memory sub-system that includes one or more components, such as memory devices that store data. The host system can provide data to be stored at the memory sub-system and can request data to be retrieved from the memory sub-system.

A memory sub-system can include memory devices that store a large amount of data (e.g., greater than one hundred (100) terabytes (TB) of data). Some memory sub-systems can have a high throughput (e.g., fifty (50) to 100 gigabytes per second (GB/s)). However, a memory sub-system that can store a large amount of data might not have a high bandwidth. As used herein, the term “bandwidth” can refer to the maximum amount of data that can be transferred within a certain amount of time. For example, a flash memory device might be a high storage capacity flash memory device that can store a large amount of data but does not necessarily have bandwidth that scales with capacity.

A high storage capacity memory device may not have a high bandwidth due to the interface of the memory device and the path through which the data travels. As used herein, the term “interface” can refer to a shared boundary across which two or more separate components of a computer system exchange information. Peripheral component interconnect express (PCIe) is an interface standard for connecting components of a computer system. The version (e.g., generation) of the interface and the amount of input/output (I/O) lanes connected to the interface can determine the bandwidth of a memory device. As used herein, the term “I/O lane” can refer to a wire connected to one or more interfaces to transfer data between the one or more interfaces.

The path through which the data travels can affect the bandwidth of the memory sub-system. For example, data can travel through different memory components and interfaces within a memory sub-system. Travelling through the different components and interfaces can decrease the speed at which the data is transferred because the data can travel through a memory component at a lower rate than it travels through an interface. Further, the different interfaces that the data can travel through can have different bandwidths. Travelling through the different memory components and interfaces can decrease the net bandwidth of a memory sub-system. As used herein, a “net bandwidth” can refer to the amount of data that was transferred over a certain amount of time as the data travelled from a starting memory device to a destination memory device.

Further, the storage capacity of memory devices can increase at a faster rate than the bandwidth of the interfaces coupled to the memory devices. This can lead to a certain amount of storage in a high capacity memory being less utilized because the data cannot be accessed fast enough to make use of the full storage capacity of the memory device. The bandwidth limitation can result in using memory devices with less capacity to avoid building unusable memory into a memory sub-system.

Some conventional approaches attempt to increase the net bandwidth of a memory sub-system and decrease the amount of unusable storage capacity by adding memory devices, such as, for instance, additional negative-and (NAND) memory devices, to the memory sub-system. Although such approaches can improve the net bandwidth of a memory sub-system, the additional NAND memory devices occupy space within the memory sub-system. Any space occupied by additional NAND memory devices decreases the amount of space available within the memory sub-system to implement memory components that perform different functions. The additional NAND memory devices can also cause the memory sub-system to consume additional power. Occupying the additional space and consuming additional power are undesirable because that results in memory sub-systems that are bigger and use more power to function as intended.

Aspects of the present disclosure address the above and other deficiencies by incorporating a plurality of ball grid array (BGA) components (e.g., ball grid array solid-state drive (BGA SSD) components) into a memory sub-system. For instance, incorporating BGA components into a memory sub-system in accordance with the present disclosure can increase both the bandwidth and storage capacity of the memory sub-system without increasing the size or power consumption of the memory sub-system. As used herein, the term “BGA component” refers to a memory component that includes memory, such as NAND flash memory and DRAM memory, firmware, and a controller chip all in a single package. For example, in some embodiments, a plurality of BGA components within a memory device of a memory sub-system can be coupled to a controller configured to perform operations on data stored in the plurality of BGA components.

FIG. 1 illustrates an example computing environment 100 that includes a memory sub-system 110 in accordance with some embodiments of the present disclosure. The memory sub-system 110 can include media, such as one or more volatile memory devices (e.g., memory device 140), one or more non-volatile memory devices (e.g., memory device 130), or a combination of such.

A memory sub-system 110 can be a storage device, a memory module, or a hybrid of a storage device and memory module. Examples of a storage device include a solid-state drive (SSD), a flash drive, a universal serial bus (USB) flash drive, an embedded Multi-Media Controller (eMMC) drive, a Universal Flash Storage (UFS) drive, a secure digital (SD) card, and a hard disk drive (HDD). Examples of memory modules include a dual in-line memory module (DIMM), a small outline DIMM (SO-DIMM), and various types of non-volatile dual in-line memory modules (NVDIMMs).

The computing environment 100 can include a host system 120 that is coupled to one or more memory sub-systems 110. In some embodiments, the host system 120 is coupled to different types of memory sub-system 110. FIG. 1 illustrates one example of a host system 120 coupled to one memory sub-system 110. The host system 120 uses the memory sub-system 110, for example, to write data to the memory sub-system 110 and read data from the memory sub-system 110. As used herein, “coupled to” or “coupled with” generally refers to a connection between components, which can be an indirect communicative connection or direct communicative connection (e.g., without intervening components), whether wired or wireless, including connections such as electrical, optical, magnetic, and the like.

The host system 120 can be a computing device such as a desktop computer, laptop computer, network server, mobile device, or such computing device that includes a memory and a processing device. The host system 120 can be coupled to the memory sub-system 110 via a physical host interface. Examples of a physical host interface include, but are not limited to, a serial advanced technology attachment (SATA) interface, a peripheral component interconnect express (PCIe) interface, universal serial bus (USB) interface, Fibre Channel, Serial Attached SCSI (SAS), Small Computer System Interface (SCSI), a double data rate (DDR) memory bus, a dual in-line memory module (DIMM) interface (e.g., DIMM socket interface that supports Double Data Rate (DDR)), Open NAND Flash Interface (ONFI), Double Data Rate (DDR), Low Power Double Data Rate (LPDDR), or any other interface. The physical host interface can be used to transmit data between the host system 120 and the memory sub-system 110. The host system 120 can further utilize an NVM Express (NVMe) interface to access components (e.g., memory devices 130) when the memory sub-system 110 is coupled with the host system 120 by the PCIe interface. The physical host interface can provide an interface for passing control, address, data, and other signals between the memory sub-system 110 and the host system 120. FIG. 1 illustrates a memory sub-system 110 as an example.

The memory devices 130, 140 can include any combination of the different types of non-volatile memory devices and/or volatile memory devices. The volatile memory devices (e.g., memory device 140) can be, but are not limited to, random access memory (RAM), such as dynamic random-access memory (DRAM) and synchronous dynamic random access memory (SDRAM).

An example of non-volatile memory devices (e.g., memory device 130) includes negative-and (NAND) type flash memory. Each of the memory devices 130 can include one or more arrays of memory cells. The memory cells can include single level cells (SLCs) that can store one bit per cell, multi-level cells (MLCs) that can store two bits per cell, triple level cells (TLCs) that can store three bits per cell, quad-level cells (QLCs) that can store four bits per cell, and/or penta-level cells (PLCs) that can store five bits per cell, among others. As used herein, the term multiple level cells is used to refer to cells configured to store more than one bit per cell (e.g., MLC, TLC, QLC, PLC, etc.). In some embodiments, a particular memory component can include an SLC portion, and an MLC portion, a TLC portion, a QLC portion, and/or a PLC portion of memory cells. The memory cells of the memory devices 130 can be grouped as pages that can refer to a logical unit of the memory device used to store data. With some types of memory (e.g., NAND), pages can be grouped to form blocks.

Although non-volatile memory components such as NAND type flash memory are described, the memory device 130 can be based on any other type of non-volatile memory or storage device, such as such as, read-only memory (ROM), phase change memory (PCM), self-selecting memory, other chalcogenide based memories, ferroelectric transistor random-access memory (FeTRAM), ferroelectric random access memory (FeRAM), magneto random access memory (MRAM), Spin Transfer Torque (STT)-MRAM, conductive bridging RAM (CBRAM), resistive random access memory (RRAM), oxide based RRAM (OxRAM), negative-or (NOR) flash memory, and electrically erasable programmable read-only memory (EEPROM).

The memory sub-system controller 115 can communicate with the memory devices 130 to perform operations such as reading data, writing data, or erasing data at the memory devices 130 and other such operations. The memory sub-system controller 115 can include hardware such as one or more integrated circuits and/or discrete components, a buffer memory, or a combination thereof. The hardware can include digital circuitry with dedicated (i.e., hard-coded) logic to perform the operations described herein. The memory sub-system controller 115 can be a microcontroller, special purpose logic circuitry (e.g., a field programmable gate array (FPGA), an application specific integrated circuit (ASIC), etc.), or other suitable processor.

The memory sub-system controller 115 can be a processing device, which includes one or more processors (e.g., processor 117) configured to execute instructions stored in a local memory 119. In the illustrated example, the local memory 119 of the memory sub-system controller 115 includes an embedded memory configured to store instructions for performing various processes, operations, logic flows, and routines that control operation of the memory sub-system 110, including handling communications between the memory sub-system 110 and the host system 120.

In some embodiments, the local memory 119 can include memory registers storing memory pointers, fetched data, etc. The local memory 119 can also include read-only memory (ROM) for storing micro-code. While the example memory sub-system 110 in FIG. 1 has been illustrated as including the memory sub-system controller 115, in another embodiment of the present disclosure, a memory sub-system 110 does not include a memory sub-system controller 115, and can instead rely upon external control (e.g., provided by an external host, or by a processor or controller separate from the memory sub-system).

In general, the memory sub-system controller 115 can receive commands or operations from the host system 120 and can convert the commands or operations into instructions or appropriate commands to achieve the desired access to the memory device 130. The memory sub-system controller 115 can be responsible for other operations such as wear leveling operations, garbage collection operations, error detection and error-correcting code (ECC) operations, encryption operations, caching operations, and address translations between a logical block address and a physical block address that are associated with the memory devices 130. The memory sub-system controller 115 can further include host interface circuitry to communicate with the host system 120 via the physical host interface. The host interface circuitry can convert the commands received from the host system into command instructions to access the memory device 130 as well as convert responses associated with the memory device 130 into information for the host system 120.

The memory sub-system 110 can also include additional circuitry or components that are not illustrated. In some embodiments, the memory sub-system 110 can include a cache or buffer (e.g., DRAM) and address circuitry (e.g., a row decoder and a column decoder) that can receive an address from the memory sub-system controller 115 and decode the address to access the memory device 130.

In some embodiments, the memory device 130 includes local media controllers 135 that operate in conjunction with memory sub-system controller 115 to execute operations on one or more memory cells of the memory devices 130. An external controller (e.g., memory sub-system controller 115) can externally manage the memory device 130 (e.g., perform media management operations on the memory device 130). In some embodiments, a memory device 130 is a managed memory device, which is a raw memory device combined with a local controller (e.g., local controller 135) for media management within the same memory device package. An example of a managed memory device is a managed NAND (MNAND) device.

The memory sub-system 110 can include a memory component 113. The memory component 113 can include various circuitry to facilitate storing a large amount of data (e.g., greater than 100 TB of data) in memory device 130 with a high bandwidth (e.g., 50-100 GB/s). In some embodiments, the memory component 113 can include multiple BGA components 112-1, . . . , 112-N (individually or collectively referred to as BGA component 112) to store data and a processing device (e.g., controller) 136 to manage the BGA components 112.

In some embodiments, the memory the memory device 130 includes at least a portion of the memory component 113. Further, the memory device 130 can include a local media controller 135 configured to execute instructions for performing the operations described herein. In some embodiments, the memory component 113 is part of the host system 110, an application, or an operating system.

In a non-limiting example, an apparatus (e.g., memory sub-system 110) can include a memory component 113. The memory component 113 can be resident on the memory device 130. As used herein, the term “resident on” refers to something that is physically located on a particular component. For example, the memory component 113 being “resident on” the memory device 130 refers to a condition in which the hardware circuitry that comprises the memory component 113 is physically located on the memory device 130. The term “resident on” can be used interchangeably with other terms such as “deployed on” or “located on,” herein.

The memory sub-system 110 (e.g., memory device 130) can include a memory component 113 having a plurality of BGA components 112-1, . . . , 112-N (individually or collectively referred to as BGA components 112), wherein each respective one of the BGA components 112 includes a plurality of NAND memory blocks (e.g., NAND memory blocks 222-1, . . . , 221-N shown in FIG. 2) a BGA component controller (e.g., BGA component controller 216-1, . . . , 216-N shown in FIG. 2), and firmware adjacent the plurality of NAND memory blocks to manage the plurality of NAND memory blocks. In some embodiments, the BGA component controller of each respective one of the BGA components 112 can manage each respective NAND memory block in that respective BGA component 112 independently. For example, the BGA component controller of a BGA component 112 can execute instructions to transfer data to and from one or more of the plurality of NAND memory blocks of that BGA component without transferring data to and from the other NAND memory blocks of that BGA component.

A processing device (e.g., controller) 136 is included in the memory component 113 to perform memory operations on the BGA components 112 (e.g., on the data stored in the BGA components 112). The memory operations can include, for instance, compute operations performed on the data stored in BGA components 112 (e.g., in the blocks of the BGA components). The processing device 136 can be coupled to the BGA components 112 via an interface. For example, the interface can include a plurality of processing device and BGA component input/output (I/O) lanes to couple the BGA components 112 to processing device 136. In some embodiments, the processing device 136 can be coupled to the interface using the same number of processing device I/O lanes as the number of BGA component I/O lanes used to couple the BGA components 112 to the interface.

A controller (e.g., memory sub-system controller) 115 can be operatively coupled with the memory component 113 to manage data transferred between a host (e.g., host system) 120 and the plurality of BGA components 112. In some embodiments, the controller 115 can perform host request operations corresponding to requests from the host 120, wherein the host request operations are different than the memory operations performed by the processing device 136. In some embodiments, memory operations to manage the BGA components 112 can be performed on the BGA components 112 while operations for fulfilling the host request can be performed on the processing device 136. In some embodiments, the processing device 136 and the plurality of BGA components 112 can be on the same memory chip. In some embodiments, the processing device 136 and the plurality of BGA components 112 are on different memory chips. Further, the controller 115 can receive a request from the host 120 to perform a memory operation on the BGA components 112. The memory operation can be performed on BGA components 112 by processing device 136, and the results of the memory operation can be transferred (e.g., sent) from processing device 136 to the controller 115, which can transfer the results of the operation to the host 120.

FIG. 2 is a block diagram of an example BGA storage for a memory sub-system (e.g., memory sub-system 110 of FIG. 1) in accordance with some embodiments of the present disclosure. The memory sub-system includes a memory component 213 having a plurality of BGA components 212-1, . . . , 212-N (BGA components 212). Each of the BGA components 212 can include a plurality of memory blocks 222-1, . . . , 222-N (collectively or individually referred to as plurality of memory blocks 222) a BGA component controller 216-1, . . . , 216-N (individually or collectively referred to as BGA component controller 216), and firmware adjacent (e.g., underneath) the plurality of memory blocks 222 to manage the plurality of memory blocks 222 (e.g., BGA component 212 can include a plurality of memory blocks 222-1, a BGA component controller 216-1, and firmware adjacent memory blocks 222-1, etc.). Further, each BGA component 212 can include a BGA component interface 214-1, . . . , 214-N (individually or collectively referred to as BGA component interface 214). In some embodiments, the plurality of memory blocks 222 of a respective BGA component 212 are exchangeable with memory blocks of different storage capacities. Further, the plurality of memory blocks 222 of each respective one of the BGA components 212 can comprise a plurality of vertically stacked NAND dies. A memory component 213 can also include a processing device 236 to perform memory operations on the BGA components 212. The memory component 213 includes an interface 232 to couple the BGA components 212 to the processing device 236. The BGA components 212 can be coupled to the interface 232 via a plurality of BGA component I/O lanes 228-1, . . . , 228-N (individually or collectively referred to as BGA component I/O lanes 228) and the processing device 236 can be coupled to the interface 232 via a plurality of processing device I/O lanes 234-1, . . . , 234-N (individually or collectively referred to as processing device I/O lanes 234). In some embodiments, the interface 232 is a PCIe interface.

Being able to exchange the plurality of memory blocks 222 of a BGA component 212 with memory blocks of different storage capacities can benefit the memory sub-system by increasing the scalability of the memory sub-system. As used herein, the term “scalability” refers to a memory sub-system's ability to increase or decrease in performance in response to changes in application and system processing demands. Memory sub-systems are being tasked with storing increasing amounts of data and performing increasing amounts of memory operations. Building scalable memory sub-systems is a cost-effective way to meet this increasing demand. A scalable memory sub-system allows for components within the memory sub-system to be exchanged for memory components that can meet the increased demand without unintended decreases in performance. In previous approaches, memory sub-systems that are not scalable might be replaced if the demands on the memory sub-system increase past the threshold of performance that the memory sub-system as currently constructed. However, replacing an entire memory sub-system is more time-consuming and expensive than exchanging components within a scalable memory sub-system. The scalability of the memory sub-system can be the memory sub-system's ability to store an increasing amount of data and perform an increasing amount of memory operations on that data without unintended decreases in the performance of the memory sub-system. Unintended decreases in the performance of the memory sub-system can include, at least, unintended decreases in bandwidth and/or storage capacity.

Exchanging at least one of the plurality of memory blocks 222 with at least one of a memory block with a higher storage capacity can increase the scalability of the memory sub-system. For example, exchanging at least one the plurality of memory blocks 222 with at least one of a memory block with a higher storage capacity can increase the storage capacity of that BGA component 212 without causing an unintended decrease in the performance of the memory sub-system. Exchanging multiple of the plurality of memory blocks 222 in each of the BGA components 222 can result in a significant increase in storage capacity in the memory sub-system without causing an unintended decrease in performance of the memory sub-system.

Increasing BGA component I/O lanes 228 of the BGA component interfaces 214 can also increase the scalability of the memory sub-system. For example, increasing the BGA component I/O lanes 228 of each of the BGA component interfaces 214 from one BGA component I/O lane 228 to two BGA component I/O lanes 228 can increase the scalability of the memory sub-system because the increased amount of BGA component I/O lanes 228 can increase the amount of data that can be transferred from the BGA components 212 to the processing device 236 within a certain period of time. This increased capacity to transfer data can allow a memory sub-system to meet increased demand for data transfers within the memory sub-system without unintended decreases in performance.

Each one of the respective BGA components 212 (e.g., the BGA component interface 214 of each respective BGA component 212) can include a plurality of channels to couple the plurality of memory blocks 222 of that respective BGA component 212 to the BGA component interface 214. The bandwidth of the channels can depend on, at least, the type of interface (e.g., BGA component interface 214), the generation of the interface, and the number of I/O lanes (e.g., BGA component I/O lanes 228) of the interface. For example, the type of interface can be a PCIe interface (e.g., a generation four (4) or generation five (5) PCIe interface), and the number of I/O lanes can be the sum of one (1) or two (2) I/O lanes from each BGA component 212. In some embodiments, the plurality of channels can have a combined bandwidth that is greater than a bandwidth of the interface 232. The combined bandwidth of the plurality of channels having a greater bandwidth than the bandwidth of the interface 232 is beneficial because it allows the interface 232 to utilize its full bandwidth. If the combined bandwidth of the plurality of channels is less than the bandwidth of the interface 232, the interface 232 would only be able to transfer data as quickly as the channels can transfer the data to the interface 232. This could result in the interface transferring data at a speed that is less than its available bandwidth.

In some embodiments, the BGA component controller 216 of each respective one of the BGA components 212 is underneath the plurality of memory blocks 222 of that respective BGA component 212. As shown in FIG. 2, the BGA component controller 216 can be between the plurality of memory blocks 222 and the BGA component interface 214. The BGA component controller 216 can perform memory operations wherein the memory operations on the BGA components 212 comprise compute operations on data stored in the plurality of memory blocks 222 of the BGA components 212.

FIG. 3 is another block diagram of an example BGA storage for a memory sub-system (e.g., memory sub-system 110) in accordance with some embodiments of the present disclosure. FIG. 3 illustrates a memory component 313 including plurality of BGA components 312-1, 312-2, . . . , 312-N (individually or collectively referred to as BGA components 312) and a processing device 336. The processing device 336 can be located in close proximity of the plurality of BGA components 312. Placing the processing device 336 in close proximity to the plurality of BGA components 312 can be beneficial by decreasing the amount of time needed to transfer data between the processing device 336 and any of the plurality of BGA components 312. Decreasing the amount of time needed to transfer data between the processing device 336 and the plurality of BGA components 312 can decrease the amount of time needed to complete memory operations on data sent from the host to the memory component 313.

The amount of BGA components 312 in a memory component 313 can vary. In some embodiments, there can be sixteen (16) BGA components in a memory component 313 and in other embodiments there can be thirty-two (32) BGA components in a memory component 313. Other embodiments can have different amounts of BGA components 312 in a memory component 313. The number of BGA components 312 in a memory component 313, as well as the type of interface in each BGA component 312, can determine the number of I/O lanes used to couple the BGA components 312 to an interface (e.g., interface 232 shown in FIG. 2). For example, if sixty-four (64) BGA components 312 each have a PCIe4 (Fourth generation PCIe) BGA component interface, each BGA component 312 can couple to the interface (e.g., interface 232 in FIG. 2) using two I/O lanes. Therefore, in this example, the BGA components 312 are coupled to the interface using 128 I/O lanes. In other embodiments, if each of 16 BGA component 312 couple to an interface using PCIe5 (fifth generation PCIe) BGA interface, each BGA interface can couple to the interface using one I/O lane. In this embodiment, the BGA components 312 can couple to the interface using 16 I/O lanes.

The number of I/O lanes used to couple the BGA components 312 to the interface can depend on the combined bandwidth of the channels that couple the memory blocks within each BGA component 312 to the interface of each BGA component 312. In some embodiments, it is desirable for the channels coupling memory blocks to the BGA component interface to have a combined bandwidth that is greater than one hundred (100) Gigabytes per second (GB/s). If the memory component interface is a PCIE4 interface, 64 BGA components 312, each with an interface including two I/O lanes, can result in channels with a combined bandwidth of 103 GB/s. However, if the interface is a PCIe5 interface, 32 BGA components 312, each with an interface including one I/O lane, can result in channels with a combined bandwidth of 103 GB/s. Further, if 64 BGA components 312 are coupled to a PCIe5 interface using one I/O lane each, the channels within the BGA components 312 would have a combined bandwidth of 148 GB/s.

FIG. 4 is a flow diagram of an example method 438 for BGA storage for a memory sub-system in accordance with some embodiments of the present disclosure. At operation 442, the method 438 can include performing, by a controller included in a memory component of a memory device, memory operations on data stored in a plurality of BGA components of the memory component, wherein each respective one of the BGA components include a plurality of memory blocks to store the data and a BGA component controller and firmware adjacent the plurality of memory blocks to manage the memory operations performed on the data stored to manage the memory operations performed on the data stored in the plurality of memory blocks. For instance, the controller, memory component, memory device, and BGA components can be controller 136, memory component 113, memory device 130, and BGA components 112, respectively, of FIG. 1. In some embodiments, the controller can allocate memory operations associated with managing the plurality of memory blocks of each respective one of the BGA components to the BGA component controller of that respective BGA component.

At operation 444, the method 438 can include transferring results of the memory operations performed on the data from the controller included in the memory component to an additional controller (e.g., memory sub-system controller 115 shown in FIG. 1) operatively coupled with the memory component. In some embodiments, the results of the memory operations performed on the data stored in each of the BGA components can be transferred from the BGA component controllers to the controller included in the memory component substantially simultaneously. The results of the memory operations performed on the data can be transferred from the BGA components to the controller included in the memory component through a plurality of I/O lanes. In some embodiments, the bandwidth of the I/O lanes between each respective one of the BGA components and the controller can be adjusted. In some embodiments, the bandwidth of the I/O lanes can be adjusted by modifying a number of I/O lanes, modifying a type of I/O lanes, or both. As stated above, each BGA component interface can have one or two I/O lanes and the type I/O lanes can be, at least, PCIe4 or PCIe5 interfaces.

At operation 446, the results of the memory operations performed on the data can be transferred from the additional controller to a host. The results can be transferred via an interface that couples the additional controller to the host. Transferring the results to the host decreases the duration of the data transfer because the results of the memory operations are being transferred to the host instead of the raw data being transferred to the host. Transferring the results of the memory operation to the host instead of transferring the raw data to the host decreases the duration of the data transfer because the results of the memory operation can include less data than the raw data. Transferring less data can result in a decrease in the duration of data transfer. This decrease in the duration of the data transfer can result in a decrease the length of time to complete memory operations within the memory sub-system.
